Low-Temperature Belt Dryer
Our dryer development team, industry consultants, and industrial experts researched current dryers on the market and identified key areas in low-temperature dryers that would benefit from improvement. The result is a simplified, operator-friendly, low-temperature belt dryer that maximizes uptime – all done in a smaller footprint.
A low-temperature sludge dryer is like a gigantic pizza oven.”

The DLT is a simple, closed-loop, hot water heating system. The low-profile design integrates modular heat exchangers into the dryer system. Depending on the plant, the DLT can be designed with a dedicated hot water boiler for natural gas or biogas. The waste heat from pyrolysis or CHP cooling water can be used to offset energy requirements.
Problem: Typical low-temp dryer designs have heat recovery systems that are:
During cleaning, the entire dryer must stop operation to complete this maintenance task.
Solution: In the DLT’s heat recovery system, each module has an individual set of heat exchangers. If a single HEX within the module requires cleaning, the DLT system continues to dry sludge. The dirty HEX can be isolated, removed and replaced with a spare. It's a simple, one-person swap of the cartridge.
